OPERATOR FAMILY and pg_dump
Hi,
If a basic operator family is created, e.g.,
create operator family of1 using btree;
shouldn't pg_dump include this in its output? If not, why?

Quoting from the pg_dump source code:
* We want to dump the opfamily only if (1) it contains "loose" operators
* or functions, or (2) it contains an opclass with a different name or
* owner. Otherwise it's sufficient to let it be created during creation
* of the contained opclass, and not dumping it improves portability of
* the dump.
I guess if it contains no opclasses and no operators either, this code
won't dump it, but isn't it rather useless in such a case?

Yes, I think it's useless, like a book cover without the contents, but
ISTM it should still be dumped (perhaps someone started defining a
family and forgot about it--oh, the puns that come to mind).
